Clinical analysis of reperfusion arrhythmias in acute myocardial infarction treated by direct PCI

Objective To analyse reperfusion arrhythmias in AMI patients treated by direct PCI. To investigate prevention and treatments so as to elevate operation achievement ratio.Methods One hundred and seventy six AMI patients underwent direct PCI; of the 176 patients, 56 presented reperfusion arrhythmias. Observations were made in the context of the different arrhythmias, relation between the time onset of the arrhythmias after reperfusion, relation of infarct size number of the involved vessels and the infarct size to the arrhythmias. Results PCI performed with six hours after AMI showed much higher incidence of arrhythmias than PCI performed six to twenty four hours after AMI (P 0.01). Multi-vessel disease AMI patients yielded a higher incidence of reperfusion arrhythmias than single-vessel disease AMI patients (P 0.05). Brady-arrhythmias appeared more in inferior infarction patients (P 0.01). No apparent connection between infarct size and reperfusion arrhythmias was noted (P 0.05).Conclusions Reperfusion arrhythmias were commonly seen in AMI patients treated by direct PCI. Early prevention and detection with appropriate treatment is the key to elevate survival rate leading to a better prognosis.
